LP3872EMP-5.0/NOPB datasheet by Texas Instruments

LP3872EMP-5.0/NOPB Frequently Asked Questions (FAQs)

• What is the maximum input voltage that can be applied to the LP3872EMP-5.0/NOPB?
  The maximum input voltage is 15V, but it's recommended to keep it below 12V for optimal performance and to prevent overheating.
• How do I ensure the output voltage is stable and accurate?
  To ensure stable and accurate output voltage, make sure to use a high-quality output capacitor with low ESR, and follow the recommended PCB layout and thermal design guidelines.
• What is the minimum input capacitance required for stable operation?
  A minimum input capacitance of 10uF is recommended, but a larger capacitance (e.g., 22uF) is recommended for improved transient response and stability.
• Can I use the LP3872EMP-5.0/NOPB in a high-temperature environment?
  The LP3872EMP-5.0/NOPB is rated for operation up to 125°C, but thermal design and heat sinking may be required to ensure reliable operation in high-temperature environments.
• How do I protect the LP3872EMP-5.0/NOPB from input voltage transients and surges?
  Use a TVS (Transient Voltage Suppressor) diode or a voltage clamp circuit to protect the input from voltage transients and surges, and ensure the input capacitor is rated for the maximum expected voltage.
